Be it known that L Geenen F. Voi'rn, :l citizen oi the United States, residing et ,lli-ladelphie7 in the county of lhiladelpl'iia :intl State of Penney Tonie, have invented certain new :unl useful Improvements in Repeating Devices ioi- 'lfellcingfMachines7 the followingl is a specification.

My invention eoneiete of aY repeating device for talking machines. One object oi my invention is to provide n device which can be quickly and easily attached to a telle jing m'lohine nil wir." will efficiently ope'rnto fr: effect the znowfnent oli the reprodnei eiemonte ol' the repen ll the record.

Fig. 12 ie :i View of a, cross arm which I may employ in combination with the ordinary form of I )lxonogrepli needle und in plan View showing ol? the parte iliusr on the line 11----11 of steal of the emeinlly construeted needle shown .in Figs. sind 8.

.Referring to Figs. 1 4to 8 inclusive, 1, represente a plete which is preiembly mede 0f sheet metal :incl includes a ring section 2 and :L solid section 3. The solid section 3 hee a turned edge 4 upon which a section 5 slides. This prei/iden] 'with n hole 7 through which the tuin table post of the talking machine eX- tenile and thus provides the eenterof rotation for' the plate 1.

The section u?, is notched, as shown at 8, on i?" inne; edge for the engagement of a. Spr-ine* detail S3 n .fh is seelireti to the Solid` .1 1, the object being to hold the centering Steetion 5 in 'various positione en the turned edge 4.

The soliti. section 3 forms e. l'ilnrnlity of rail.; 10. sind rails being eoltleretl throughout e portion of their lengitli mlieeent the trete-ffl et 11. These rails, are preferably mafie of thin reelient metal, their inner esule l2 being reely movable in e plone parallel. with the upper surface 'of the plete l.

Aninner ruil 3 ie eeeurefl. to the solid section 2%, e et enti projects beyond the 'turnecl edge 4. su. ehownat le. An' extreme v0ntei"1 'f;il 15 is secured, preferably through eeetion 2, andthe upper of the rails slant or 2, 3, and 8). As iilnst-eted in 1, all of the rail; are igiirved, :unl at their ends 1- arespaeed 'farther apart than at the ends 12. The curvature and .erre ffenent olf' he rails .is .such that at the entle- 16, the re le are spaced relatively in" npztrtend groei. 'lly become closer together until :ill thel intermediate rails open into the space 18 between the mil 13 mtl ruil A15. `Thus. the rails are .located `in n. snl'istantielly illustrated in Fig. 1.

T he ring section i?. lia-S :in overturned p01*-- tion 19 on its upper surface which provides e slifleway for n. carriage 20. This carriage 20 supports e member 21 which in turn provides f. gnidewey for en erm 22 which is preforably'nngrular in cross @eration es clean-ly illustrated in Fia. 5. y

The member 21 een be Soldered or othere. support for turned edge 4 as illusspil-ei formation as clearlyl :fseetion 5 hes a. projection 6 oi all of' the rails extend" wi secured to the carriage 20, so that said mem r and the carriage move as a unit within the slideway 19, and the arm 22 is designed to slidelongitudinally toward and from the center of the plate 1. A coiled spring 23 has one end attached to the carriage 20 and the other end attached to the plate l asf-'shown at 24. This spring 23 serves asfa buffer or to compensate for the ]ar caused by the engagement of the arm 22 with certain of the recording elements of the talking machine as will hereinafter be Inore fully described.

InY the use of my invention, I` preferably provide a 'four-pointed needle, one leg of which can be inserted Within the usual needle carrier on a talking machine so that thepoint 25 will engage the grooves of the record, the other .leg 2 6 extending substantially at right angles'thereto and being operative when engaged by any of the tapered portions 17 of the rails to be lifted so that the point 25 is raised above the level o'f the record, and also above the upper surface of the platel.

I preferably cover the bottom of the plate 1 with soft material such as felt or other cloth, and provide a balancing pad 27 which depends from the lower surface of the'plate 1. The location of this pad is dependent upon the balancing point of the entire device and can be made of lsoft material so as not to injure the record by coming in contact with it.

' In order to properly locate this pad, I first balance the device, for Aexample as upon the end of a finger of one hand, and on the spot upon which the device balanceson the linger, I paste or otherwise secure the balance pad. The construction is such that the balancingpad normally'forms the sole support of the device on'the record so that the major portion of the device is held in a position .spaced from the upper surface of the record. Furthermore, the general shape of the device is such that the ba anclng point upon which the pad is mounted is adjacent' vthe center olv the plate 2 vso that the pad rests upon the record'near the center of the latter where 'there are no sound reproducing grooves.- v In this manner the reproduction portion of the record is not injured byv the rotation of the record under the device, since the record engages'the.' balancing pad and rotates thereunder. A

In the operation of my invention, the plate 1 is placed upon the record of the talking machine, the post of the talking cated'a )acentthe .initial recordinggroovemachine extending through the hole 7 of the- 'centerin secti on'5,the space 18 being -loof the record. :This position can be attained by slidingthe section 5 longitudinally alon the turned edge 4 and 'against' the action o. the spring detent 9. The arm `22 41S then the arm 22.

until its inner end 28 lies directly above the last recording groove of the record, The needle point 25 is then inserted in the usual manner within the outer groove and -f the needle carrier is permitted to rest against the edge 29 of the arm 22.

The rotation of the record. will. cause the'vv needle carrier to move inwardly along the edge 29 of the6 arm 22 during which time the record is being produced. When the needle carrier has reached the end 28 of the v"arm 22 and becomes freethereof, the record'vvill rotate the entire plate 1 and cause thej/ltransversely extending arm 26 of the needle ,to be engaged 4fby the tapered portions 17 of the railswhich are moving Within the 'path octhe upper edges of the rails 13 and 15 where the latter forms'the space 18 and are close together as shown on the left hand side of Fig. 1, thus the arm 22Will again engage Vthe needle'carrier and the. rails 13 and 15 Will return the needle to the initial recording groove and the operation will be repeated.

The spring 23 serves to prevent any harsh action or inJury to the machine, and relieves the jar which would' otherwise occur if the arm 22'Were made rect to the plate 1.

It Wlll be noted that my invention can be employed to suit records of various diam-v eters, it only being necessary to move the centering slide 5 along the turned edge 4, and furthermore, the arm 22sis made sui- -ciently long vto accommodate various 'areas permanent or secured di* of recording grooves on various size records.

Instead of' having the specially constructed four pointed need-le as above described, I can use a cross arm for example, as `shown in` Fig. 12, and this cross arm can be used with the usual form of 'single pointed needle now-in common use merely by inserting the stem 30, together.with the needle, Withvin the needlecarrier, and when so used the transversely extending arms v31 and -32 will be engaged by the tapered portions 17 of the rails and the needle will be lifted above the record and above the top surface of the plate 1. 4In the Fig. 9, I have illustrateda-spring 33 'which is preferably made of fiat resilient metal and this spring is positioned 'to the rearl of form of my linvention shown in hespring 33 is mounted iniso ends ere free to flex, I

supports 34 on the ring Section 35 which corresponds in all other respects with the ring section 2 above mentioned.

burtliermore, in this form of my invention, instead of the erm22-fbcing pulled by n, spring, uis for exemple the spring 23, it is backed by the sprin B3, and the sii-ing 33 therefolie a lte to ou; 4lion and to tu e up the j er caused y the engagement of the drin 22 with thfheedle In. all ot er respects the forni of my invention shown in Fig. 9 is similar lo that above described in. connection with Figs. 1 to 8 inclusive, and I have therefore giver( :similar parts corresponding reference nn'- merels. f

By mounting l'lie mils so tlinl' their inner avoid any nach Hcrupingnetion :ind undesirable neinA since llie 'rails ,gradually eoi'npel 'the nei-:difv to ne relurnec'l'to the initial position.

Furtherznore. iii' lmlnnring the more iE: uornmlly kept free ofthe reproilovingr por lion ol' the record und ille weight oi" tin parte is suoli that. the lmlzinving pod comm within lli@ eprice oii lflle record not orropieil b i' tile lrepli-odneingg groot-e.
